I think that expectations are strongly shaped by what
we have around us.

I have dealt with a lot of code with get methods that issue
no complaint if you try to get what isn't there. None of
it will autocreate just to succeed. So for me a get method
that creates is very surprising.

As for which is stronger, well the fantasy connection is
one reason I think in terms of summoning being stronger.
The next image that comes to mind is comparing getting a
person, when that person can just say, "Sorry, I'm busy"
versus issuing a legal summons where if you don't show up,
you can go to jail.

But still, if your expectations are opposite, the name is
unclear. I should therefore change it... *sigh*

As for your class, I would have named it something like
WaitingFor (or with the captitalization I use, waiting_for).
But then again naming things is my least favorite part of
programming...
